According to conclusions of Georgian geographers, the state border of Georgia is depicted differently on topographic maps issued during various years of the 20th century. There is no indication of the scale that was used for the map showing official border data. The location of some geographical sites indicated in some scientific studies and on small-scale maps (including schools) also triggers uncertainty.

Over the past years nanotechnology has been established as one of the most dynamically developing interdisciplinary sciences. Potential applications for nanomaterials in medicine and pharmacology are many and this has become a priority direction that will lead to solutions for some of the most painful health problems. However, modern nanotechnologies necessitate the creation of new directions of scientific research—uniting the scientific achievements of nanotechnology and biotechnology has led to the creation of a new discipline – nanobiotechnology. This will lead to nanoconstructions that can manage biosystems at a molecular level. Nanofluids consisting of magnetic nanoparticles are of special interest.

DNA research is one of the major tasks for scientists working at the molecular and atomic physics. One of the key components of DNA is protein, and its transfer processes play a major role in the course of chemical and biochemical reactions. This is confirmed by prototropic tautomerism, hydration, dehydration and especially proton transfer between nucleotide bases that cause mutations in DNA. Scientists are especially interested in researching proton transfer mechanisms between the atoms separated by one, two or three chemical bonds as it is directly linked with the mutational processes ongoing in biologically active heterocyclic compounds. Frequently, proton transfer takes place in an organic molecule, however the mechanisms of this process are not yet known. Many scientists are working over this problem internationally including those in the Physical Chemistry Department of Tbilisi State University, led by Professor Jumber Kereselidze.

Stress is closely linked with the process of industrialization and it can cause or significantly aggravate human diseases and disorders including cardio-vascular disease, disorders of the immune system, impaired neurodegenerative processes and tumors. Stress has a negative influence on labor capacity by causing short term memory loss, absenteeism, poor concentration, increased aggressiveness, etc. The American Psychological Association (APA) describes chronic stress as “the stress of unrelenting demands and pressures for seemingly interminable periods of time.”  The major causes of human mortality are connected with stress--like heart and lung diseases, cancer, accidents, cirrhosis and suicide. Georgian scientists have joined the world of research on this subject.
